I have probably one of the weirdest problems with Java ever.
I tried to start some application say Wrapper (i.e. I2P router) and got the following:
-piece of the router log-

On the developers forum I was told that it could be possibbly that I hadnt a loopback address at all.
Which is unlikely to be.
I have other application which work with the loopback address, also I switched off the IPv6, put all the neccessary options to ignore IPv6 in wrapper.
Next I tried to start wrapper under the admin aacount, tried to install all the stuff including Java under the admin account — completelly useless.
I didnt find any reasonable answer on any foruma. Always it was about the firewall. But I turned it off, I deinstalled it, switched Windows firewall off under the admin account.
And also I opened all the necessary ports on my wi-fi router. Other programs like Privoxy work well with loopback connection and ports, but if I check online ofcourse I get a message that all my ports blocked, which I consider as to be wrong.
My operating system is Windows 7 64bit, my wi-fi router is Speedport 723v.
I thank everybody in advance for answers.
The Invisible Internet Project (I2P) is a fully encrypted private network layer that has been developed with privacy and security by design in order to provide protection for your activity, location and your identity. The software ships with a router that connects you to the network and applications for sharing, communicating and building.
Install I2P on Debian
apt update
apt upgrade
apt install apt-transport-https curl
apt-get install i2p
- ALLOW PORTS 7657 and 7658
iptables -I INPUT -p tcp -m tcp --dport 7657 -j ACCEPT
iptables -I INPUT -p tcp -m tcp --dport 7658 -j ACCEPT
- ROUTE THE INCOMING DATA TRAFFICE FROM 195.15.219.25 TO LOCALHOST (127.0.0.1)
vi /etc/sysctl.conf
Add following line at bottom of sysctl.conf
ipv4.conf.eth0.route_localnet=1
Save and exit
Run Following commands:

- TUNNEL CONFIGURATION BETWEEN I2P AND EXISTING APACHE SERVER
http://195.15.219.25:7657/config in browser then click on Hidden Service Manger:
Then Click on Tunnel Wizard
Select Server Tunnel Then Next:
Select HTTP:
Type the name of Tunnel
Host : 127.0.0.1
Port: 80
Select check box
Save tunnel
After Finishing it will be shown Hidden Service Manager as shown below, start service if it is not started yet:
In above pic destination under green box is your b32.i2p address through which you can access your appache hosted websites i.e. your nextcloud website.

- HOW TO ACCESS WEBSITE THROUGH ANDROID PHONE:
- Download and install invisible in your android phone from your mobile
- Open installed application and start service
- Open browser and access your i2p website
- HOW TO ACCESS I2P WEBSITE THROUGH WINDOWS PLATFORM
Step1:
Download package named i2pd_2.39.0_win64_mingw.zip from following link:https://github.com/PurpleI2P/i2pd/releases/tag/2.39.0
Step: 2
Extract package i2pd_2.39.0_win64_mingw.zip
Go into the folder i2pd_2.39.0_win64_mingwàContrib
Moves all files and folder exist in contrib folder to main i2pd_2.39.0_win64_mingw folder
Step 3:
Open i2pd.conf in notepad uncomment following section and make change as shown below
[i2cp]
## Uncomment and set to ‘true’ to enable I2CP protocol
enabled = true
## Address and port service will listen on
address = 127.0.0.1
port = 7654
Now start i2pd.exe
Step 4:
Create another shortcut of google chrome and edit following line in target: –proxy-server=”127.0.0.1:4444″
Now open the shortcut of google chrome that you have modified and access your i2p website:

Logs:
[istener:7654] er.client.ClientListenerRunner: I2CP error listening to port 7654 – is another I2P instance running? Resolve conflicts and restartResolution:Initially speed was slowing down due to multiple instances on port 7654 therefore all hidden services deleted that were created during tests except one NextCloud Tunnel
Also we have changed the default port 7654 of i2p to 1111 (that is an option to avoid above error)
log-router-0.txt
Logs:
Refusing connection since peer is throttled by per-peer limit of 80 per hour:
[127.0.0.1:80] reaming.impl.ConnectionManager: Refusing connection since peer is throttled by per-peer limit of 200 per day
From above logs observed that host shown down once access limit crossed by 80 per hour or 200 per day. So after increasing limit we have resolved this issue.
To do this open hidden service manager and click on NextCloud Tunnel that we have created
Then scroll down and open Server throttling option and we have increased the limits as shown below
By setting up above parameter we have successfully fix the issue which are mentioned in logs.
To further improve the speed issue, there is an option to reduce the hop count. Number of hop count more means high anonymity but less performance. So we have reduced hop count of tunnel Nextcloud which we created as shown below to improve the speed:
So speed much improved than before after performing above troubleshooting.
Conclusion:
I2P is much secure and recommended but its speed cannot be compared with direct hosting servers. Many people feel that the I2P network is way too slow. It is understandable, but there are good reasons that I2P is supposed to be slow. Firstly, since I2P employs garlic routing technique, your data typically have to go through 6+6=12(!) different routers for anonymization. It decreases the network speed significantly.

У меня, наверное, одна из самых странных проблем с Java.
Я попытался запустить некоторое приложение, скажем, Wrapper (т.е. Маршрутизатор I2P) и получил следующее:

На форуме разработчиков мне сказали, что возможно, что у меня вообще нет loopback-адреса.
Это вряд ли будет.
У меня есть другое приложение, которое работает с адресом loopback, также я отключил IPv6, поставил все необходимые опции, чтобы игнорировать IPv6 в оболочке.
Затем я попытался запустить упаковку под администратором aacount, попытался установить все содержимое, включая Java, под учетной записью администратора — совершенно бесполезно.
Я не нашел разумного ответа на любом форуме. Всегда было о брандмауэре. Но я отключил его, я деинсталлировал его, отключил брандмауэр Windows под учетной записью администратора.
А также я открыл все необходимые порты на моем wi-fi маршрутизаторе. Другие программы, такие как Privoxy, хорошо работают с loopback-соединением и портами, но если я проверю онлайн-курс, я получаю сообщение о том, что все мои порты заблокированы, что я считаю неправильным.
Моя операционная система — Windows 7 64bit, мой Wi-Fi-маршрутизатор — Speedport 723v.
Я благодарю всех заранее за ответы.

На форуме разработчиков мне сказали, что, возможно, у меня вообще нет петлевого адреса. Что вряд ли будет. У меня есть другое приложение, которое работает с петлевым адресом, также я отключил IPv6, поставил все необходимые параметры для игнорирования IPv6 в обертке. Затем я попытался запустить обертку под учетной записью администратора, попытался установить все, включая Java, под учетной записью администратора — совершенно бесполезно.
Ни на одном форуме не нашел вразумительного ответа. Всегда речь шла о брандмауэре. Но я его отключил, удалил, отключил брандмауэр Windows под учетной записью администратора.
А также я открыл все необходимые порты на своем wi-fi роутере. Другие программы, такие как Privoxy, хорошо работают с петлевым соединением и портами, но если я проверяю онлайн, конечно, я получаю сообщение о том, что все мои порты заблокированы, что я считаю неправильным.
